About this file
This is a Questions and Answers document for the US Army Corps of Engineers Helicopter Herbicide Spraying solicitation (W9128F26QA066). The document addresses contractor inquiries regarding project scope, methodology, and operational requirements for aerial vegetation spraying on the Missouri River.
The project is a recompete of previous contract W9128F25PA091 and permits the use of drones as an alternative to helicopter spraying, provided vendors can obtain required permits from the National Park Service for operations on the Missouri National Recreation River (which includes 39-mile and 59-mile sections within the spray zones). Vendors without drone permits must maintain an actual helicopter spray unit as backup. Key operational requirements include: delivery of spray track shapefiles and flight/spray path data in shapefile and KMZ formats; completion within approximately five weeks; prohibition on spraying when wind exceeds 10 mph; and daily treatment capacity of 300-500 acres. The spray areas feature irregular shapes that may prevent line-of-sight drone operations, necessitating flexible operational planning by the contractor.

1. Is there any incumbent/recompete or this is a brand-new project? If yes, could you please provide us with their award number or even if the customer bought similar services in the past.
This requirement was previously serviced via: W9128F25PA091
2. Can we use drones for the project?
Yes, drones could be used if they meeting the following requirements:
· The National Park Service requires a permit for any drone flights taking place on the Missouri National Recreation River, of which there is a 39-mile section and a 59-mile section in our spray zones. If the vendor cannot secure the proper permits from the National Park Service, they will need to have an actual helicopter spray unit available as a backup solution.
· The vendor will need to provide shapefiles of spray tracks where the herbicide was put down on the ground. Vendor will need to provide flight path data as well as spray path data in the form of shapefiles and kmz files.
· The spray areas have very irregular shapes (e.g., they are not uniform rectangles or other uniform polygons like a typical farm field). Line-of-sight operation may not be possible in many of the spraying situations.
· The contractor will need to complete this work within about five weeks time. They cannot spray when the wind exceeds 10mph. Must be able to treat 300-500 acres in a day.
